  1. Chapter 1 Introduction to RF and Wireless Technology • 1.1 A Wireless World • 1.2 RF Design is Challenging • 1.3 The Big Picture Behzad Razavi, RF Microelectronics. Prepared by Bo Wen, UCLA

  2. Chapter Outline • Wireless Communication • in Life • Trend in RF Development • Multitude of Disciplines • RF Trade-offs • Demand for cost and performance • TX and RX Big Picture of RF System RF Design Challenges A Wireless World

  3. A Wireless World High-speed wireless links (WiFi, Bluetooth) allow seamless connections among device and appliance.

  4. Explosive Growth of Wireless Communication The affordability of low cost and multiple functions finds its roots in Integration Performance of RF circuits has also improved.

  5. RF Design is Challenging: Multi-discipline • RF design draws upon a multitude of disciplines.

  6. RF Design is Challenging: Trade-offs • RF circuits and transceivers must deal with numerous trade-offs. • Demand for higher performance, lower cost and greater functionality

  7. The Big Picture: RF Communication RX: Sense small signal (amplify with low noise) TX: Drive antenna with high power level

  8. The Big Picture: Generic RF Transceiver • Signals are upconverted/downconverted at TX/RX, by an oscillator controlled by a Frequency Synthesizer
